The correct answer is: D. Mitathal
Mitathal is a village in the Hisar district of Haryana, India. It is located about 100 kilometers from the state capital, Chandigarh. The village is known for its archaeological remains, which date back to the Mauryan period.
In 1954, a team of archaeologists from the Archaeological Survey of India (ASI) excavated a stupa at Mitathal. The stupa was built in the 3rd century BCE by the Mauryan emperor Ashoka. It is one of the largest stupas in India, and it is believed to have been a major pilgrimage site for Buddhists.
The stupa at Mitathal is made of bricks and mud. It is about 30 meters in diameter and 10 meters high. The stupa is surrounded by a moat and a wall. The wall is made of bricks and it is about 2 meters high.
The stupa at Mitathal was excavated in several phases. The first phase of excavation was conducted in 1954. The second phase of excavation was conducted in 1955. The third phase of excavation was conducted in 1956. The fourth phase of excavation was conducted in 1957.
The excavation of the stupa at Mitathal revealed a number of important artifacts. These artifacts include a number of Buddhist sculptures, a number of terracotta figurines, and a number of coins. The Buddhist sculptures date back to the 3rd century BCE. The terracotta figurines date back to the 2nd century BCE. The coins date back to the 1st century BCE.
The excavation of the stupa at Mitathal has provided important information about the history of Buddhism in India. The stupa is a reminder of the importance of Buddhism in the Mauryan period. The artifacts that were found at the stupa provide important information about the art, religion, and culture of the Mauryan period.
The other options are incorrect because they are not places in Haryana where Mauryan stupas and relics have been found.
